Description

Technical Field

[0001] This utility model belongs to the field of dump truck technology, specifically relating to a hydraulic cylinder crossbeam assembly and a mining dump truck. Background Technology

[0002] The lifting system of a mining dump truck is a key working mechanism for achieving rapid unloading of goods. Therefore, the crossbeam assembly used to support the lifting cylinders directly affects the lifting stability and operational reliability of the entire vehicle.

[0003] In existing technologies, to meet stability requirements, the crossbeam assembly is typically fixed to the subframe using thick steel plates welded together. However, this method involves a large amount of material, resulting in a bulky structure that increases the vehicle's weight and operating energy consumption. Furthermore, its structural rigidity is insufficient, making the crossbeam assembly prone to deformation under the heavy working load of the hydraulic cylinder, thus reducing the stability of the lifting process.

[0004] Furthermore, the welding connection method makes assembly and disassembly extremely difficult, increasing maintenance costs and time. It also fails to effectively utilize the space within and around the crossbeam, making it impossible to provide a stable mounting position for the controller and limiting the space available for adding other configurations to the vehicle. Utility Model Content

[0012] Preferably, it includes: Multiple second reinforcing plates are vertically disposed on the bottom surface of the L-shaped support plate and spaced apart along the length of the upright plate.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] The terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: like Figure 1 As shown in the figure, this application discloses a hydraulic cylinder crossbeam assembly, which is fixedly installed on the subframe of a dump truck and is mainly used to connect and support the lifting hydraulic cylinder to realize reliable lifting and unloading of the cargo box; its specific structure includes: two upright plates 1, a U-shaped bottom plate 2, an L-shaped support plate 3 and multiple support members 4.

[0025] Two vertical plates 1 are arranged horizontally side by side at intervals, forming the width and basic framework of the beam assembly; and each vertical plate 1 has a U-shaped groove 101 at the bottom of one end and an L-shaped groove 102 at the top of the other end.

[0026] The cross-section of the U-shaped base plate 2 is U-shaped with the opening facing downwards. This U-shaped structure has excellent bending stiffness, ensuring load-bearing strength, and can significantly reduce weight compared to thick steel plates. The two ends of the U-shaped base plate 2 are respectively embedded and fixed in the U-shaped grooves 101 of the two upright plates 1. This embedding method provides strong shear and torsional resistance, ensuring that the thrust of the hydraulic cylinder can be effectively transmitted to the entire assembly. Multiple first mounting holes 201 are opened on both side walls for bolt connection with the subframe.

[0027] Specifically, the shape and size of the U-shaped groove 101 are adapted to the outer contour of the U-shaped base plate 2, which enables the two to be accurately positioned and fully fitted, ensuring the convenience and accuracy of the assembly and welding process. It also greatly increases the contact area and can effectively distribute the load, greatly improving the overall rigidity and load-bearing capacity. Furthermore, the fitting form constitutes a high-rigidity node, ensuring the structural strength.

[0028] It should be noted that the subframe has a rectangular cross-section, and the U-shaped base plate 2 is tightly fitted onto the upper part of the subframe during installation. This enables rapid installation, precise positioning, and initial fixation, improving the convenience of subsequent fastening operations. It also forms a three-sided wrapping structure, significantly increasing the contact area and distributing the load applied by the lifting cylinder evenly onto the subframe, avoiding local stress concentration, improving installation rigidity and connection reliability, and providing a basis for detachable connection methods.

[0029] L-shaped support plate 3 is embedded and fixed in the L-shaped groove 102 of the two upright plates 1 to provide an installation position for the controller. One side extends outward in a direction perpendicular to the surface of the upright plate 1 to form an extension area 31, ensuring that the controller, which occupies a large area, can be stably, reliably and adequately supported.

[0030] Specifically, the shape and size of the L-shaped groove 102 are adapted to the outer contour of the L-shaped support plate 3, thereby providing precise positioning and stable lateral support for the L-shaped support plate 3, which can effectively transfer and distribute the weight of the controller to the upright plate 1, ensuring the rigidity of the assembly under additional load and the stability of long-term use.

[0031] Multiple support members 4 are spaced apart along the length of the vertical plate 1 on the bottom surface of the extension area 31 and connected to the adjacent vertical plate 1. This is used to effectively transfer and distribute the load on the extension area 31 to the adjacent vertical plate 1, avoiding stress concentration, thereby enhancing the structural strength and deformation resistance of the extension area 31 and ensuring the stability and reliability of the equipment installed on it.

[0032] This utility model, through the embedded and fixed design of the upright plate 1, U-shaped base plate 2, and L-shaped support plate 3, ensures the overall structural strength and load-bearing capacity of the assembly and achieves lightweighting. Furthermore, by utilizing the clamping fit between the U-shaped base plate 2 and the rectangular subframe, as well as the bolt connection, it enables rapid installation, precise positioning, and initial fixation of the assembly, improving the convenience of disassembly and maintenance, avoiding local stress concentration, and enhancing installation rigidity and connection reliability. Finally, by combining the L-shaped support plate 3 with the support member 4, a stable installation position for the controller is provided while ensuring structural strength, achieving efficient space utilization and functional integration, and providing more space for other configurations of the vehicle.

[0033] In some embodiments, such as Figures 1 to 3 As shown, it includes: Two first reinforcing plates 5 are vertically arranged on both sides of the top surface of the U-shaped base plate 2, which can significantly enhance the local stiffness and buckling resistance of the top surface of the U-shaped base plate 2. The two ends of the first reinforcing plates 5 are respectively connected to the two vertical plates 1, thus forming a frame structure, which can more evenly transfer the lifting load borne by the vertical plates 1 to the U-shaped base plate 2, avoiding excessive stress concentration at the connection point. The first reinforcing plates 5 are perpendicular to the vertical plates 1, thus forming a three-dimensional vertical structure, thereby enhancing the overall rigidity, torsional performance and load-bearing stability of the assembly, and effectively suppressing deformation in all directions.

[0034] Through the above design, the first reinforcing plate 5, the upright plate 1 and the U-shaped base plate 2 form a stable frame structure that supports each other, thereby efficiently transferring and distributing the load acting on the two upright plates 1 to the entire assembly, thus improving the overall rigidity, deformation resistance and load-bearing stability.

[0035] In the above embodiments, such as Figure 1 and Figure 3 As shown, the top surface of the U-shaped base plate 2 has multiple first wire-passing holes 202 between the two first reinforcing plates 5, and the multiple first wire-passing holes 202 are located between the two upright plates 1.

[0036] The above design provides a centralized and protected through-channel for cables, improving the orderliness and reliability of cabling, avoiding interference between cables and moving parts, and enhancing the lightweight effect of the assembly while ensuring the overall structural strength.

[0037] In the above embodiments, such as Figure 1 As shown, it includes: Two supporting channel steels 6 are located on both sides of the top surface of the U-shaped base plate 2 and between the two first reinforcing plates 5. They are used to provide a stable and flat supporting base for the lower support of the oil cylinder and to prevent the top surface of the U-shaped base plate 2 from deforming in this area. This significantly enhances the local rigidity and disperses the concentrated load of the oil cylinder. The vertical plate 1 has two sets of second mounting holes 103 corresponding to the support channel steel 6. The number of second mounting holes 103 in each set is preferably four in a rectangular distribution, which ensures a stable connection and reduces stress concentration. They are used for bolt fastening connection with the lower support of the oil cylinder.

[0038] Through the above design, the lifting load of the hydraulic cylinder can be effectively distributed to the frame composed of the first reinforcing plate 5, the U-shaped base plate 2 and the upright plate 1, which improves the local rigidity and impact resistance of the installation area. Furthermore, by using a modular bolt connection method, the hydraulic cylinder lower support can be quickly disassembled and accurately positioned, which improves the convenience of maintenance and the reliability of the structure.

[0039] In this embodiment, as Figure 1 As shown, it also includes: Four limiting blocks 7 are arranged in pairs on two upright plates 1, and the two limiting blocks 7 on each upright plate 1 are located on both sides of the two sets of second mounting holes 103 on the upright plate 1.

[0040] The above design provides a reliable limit for the lifting cylinder, effectively preventing it from deviating from its position during installation. It ensures that the second mounting hole 103 and the bolt hole on the lower support of the cylinder can be aligned, improving the convenience and accuracy of installation. It also avoids lateral swaying of the lifting cylinder due to vibration during use, thereby enhancing connection stability and long-term safety.

[0041] In some embodiments, such as Figure 3 As shown, it includes: Multiple second reinforcing plates 8 are vertically arranged on the bottom surface of the L-shaped support plate 3, which can effectively resist vertical bending deformation, provide stable support, and are spaced apart along the length of the vertical plate 1 to form continuous and uniform support, avoiding local stress concentration, ensuring overall rigidity, and achieving lightweighting. Furthermore, the two ends of each second reinforcing plate 8 are fixedly connected to the two vertical plates 1 respectively, which can efficiently transfer and distribute the load of the L-shaped support plate 3 to the two vertical plates 1, greatly enhancing the overall integrity and torsional rigidity of the assembly.

[0042] The above design greatly enhances the load-bearing rigidity and deformation resistance, ensuring that the L-shaped support plate 3 can maintain structural stability after the equipment is installed on the top surface. It can also efficiently transfer local loads to the two vertical plates 1, optimize the stress distribution, and ensure the overall structural strength and reliability.

[0043] In some embodiments, such as Figure 3 As shown, a second wire-passing hole 301 is provided on the L-shaped support plate 3. The second wire-passing hole 301 is located in the area of ​​the L-shaped support plate 3 near the U-shaped bottom plate 2 and is located between the two upright plates 1.

[0044] The above design provides a concealed and protected routing channel for the controller's cables and conduits, effectively avoiding the risk of damage and interference that may be caused by exposed wiring, improving wiring reliability, and also enhancing the neatness and integration of the overall vehicle layout.

[0045] In some embodiments, such as Figure 3 As shown, the support member 4 includes: Two right-angled plates 41 are arranged in parallel and spaced apart. One right-angled side of each right-angled plate 41 is connected to the bottom surface of the extension area 31, and the other right-angled side is connected to the side surface of the adjacent upright plate 1. This forms the most efficient force transmission path, which can efficiently transfer the vertical downward load borne by the extension area 31 to the upright plate 1, thereby enhancing the bending resistance of the extension area 31 and preventing it from sagging and bending. The edge plate 42 is connected to the outer edges of two right-angle plates 41 on both sides, and its two ends are connected to the bottom surface of the extension area 31 and the side surface of the adjacent upright plate 1, respectively, to form an integral box-shaped structure. This greatly improves the torsional and bending stiffness of the support member 4 itself, and can distribute the load more evenly on the upright plate 1, reduce local stress concentration, and make the structure more stable and durable.

[0046] The above design enhances the structural stiffness and resistance to bending and torsion of the extension zone 31, effectively preventing it from vibrating or sagging under load. It also evenly transfers the load of the extension zone 31 to the vertical plate 1. Furthermore, while ensuring structural strength, the hollow design achieves lightweighting, ensuring the long-term stability and reliability of the extension zone 31.

[0047] Based on the above embodiments, such as Figure 3 As shown, a weight-reducing opening 4201 is provided on the edge banding plate 42.

[0048] Through the above design, while ensuring the rigidity of the box-shaped structure of the support component 4, redundant materials are reduced, and the key parts are made lighter, thereby reducing the weight and material cost of the assembly.
